Thanks for your bugreport! (I'm not maintainer of this package, but I'll
comment anyway.)

This hunk is OK.

This doesn't look good. GetMagickFileList is called in a loop and
InitializeMagick is supposed to be run only once.
And in fact, after applying your patch, psiconv still crashes for me
with the following traceback:
